I am incredibly late, but the only album from Kendrick I could see being called generic is DAMN. If you can listen through good kid and to pimp a butterfly and think what he accomplished with the overall stories presented there is generic, I uh don't trust your rap taste. For individual songs, Sing About Me, Mortal Man, etc. are example enough

That's nice and everything, but there's a big, big problem about that: people would still complain they churn the same grog over and over. It might be a clichť statement, but I assure you it would be just like that, and I bet those poor three chaps would get tire soon of not attempting to do something different, even if it's just for fun. That means they would even go out with a feeble fart. I'd rather have them making a bad experiment while trying something new because they want to, than making the same album all over again to fulfill the whiny wishes of an exclusive group of people, thanks.
Also, aren't they having fun now? It seems to me they're pretty happy with what they're currently doing. Whether we may like it or not, that's another matter, of course.

Maybe they're happy with the music they're making, but it's hard not to look at videos of the last arena tour and compare them to ones from the small gigs, or even ones from the T2L tour, and not feel like the band looks super bored in comparison.
I posted some videos from my 2012 MotP and my 2016 MotP and the differences were pretty shocking. (If interested in YTing, the first in Minneapolis, the latter in Philly or DC.)

As for people complaining no matter what they put out, that's not really a foregone conclusion.
There's plenty of bands that have stuck close to their formula for decades and still retain tons of happy fans. Muse's obstacle with that is they've already deviated enough to really alienate people, and it's hard to win them back.
On the other hand, look at a band like AFI. This is a band that's changed in a massive, massive way over the years (and at one point rather abruptly) with a big contingent of fans that will never warm up to the "new" music.
However, the band's gigs are loaded with those old fans because the band still plays super old, deep tracks. Muse could easily have done something like that to retain fans; just make it worth people's while to show up and see some bizarre old song.

Everyone focused on the other comments but I'd agree in wanting the band to just settle instead of continuing this mainstream appeal attempts. They seem happier when they just let loose. Even for music The 2nd Law did not age well here but we look back on the era fondly because they had fun and it showed.

ver said pander, I said have fun and stop trying to be popular. The 2nd Law was wild experiments in their modern sense that didn't blow anyone away but it was still a good era.

Lately there's been a growing divide between the fan shows and then big shows, and they want to go even further with that. Is that not pandering?

Basically the point Iíve been trying to make but I kept getting drawn into a Kendrick debate Iím not interested in having! Shouldnít have bothered to drop names haha

So pessimistic.
Even if all the first three/four singles are duff, if they decide to settle on maximum amount of songs they claimed (12) for the , we'd still have 8/9 songs to look out to.
Between Algorythm being a piano-driven song, The Dark Side being the band's current favourite one, and the "Herrmann-like" strings mentioned in that IG post, I'm still looking forward to what they could do, "traditional song structures" or not.
